2 Claims. 1

This invention relates to portable saws, and more particularly to a portable saw for cutting into desired lengths logs to be used for pulp wood or ties or the like.

The object of the present invention is to provide an improved portable saw of the type indicated, peculiarly adapted to being maneuvered on the rough ground and in the underbrush commonly encountered where the logging operations are in progress, so that it can be readily positioned with respect to the fallen logs to cut same at desired points without the necessity of moving the logs either to level the same or change their position on the ground.

Further objects will appear in the course of the following detailed description.

The invention consists in the novel construction, arrangement, and combination of parts hereinafter more particularly described and claimed.

One sheet of drawings accompanies this specification in which like reference characters indicate like parts throughout.

In the drawing:

Figure 1 is a side elevation of the improved portable saw;

Figure 2 is a plan view of the saw;

Figure 3 is a vertical transverse cross-section taken on line 3-3 of Figure 1.

In accordance with the present invention, a suitable framework is provided including substantially parallel handle I-I connected at their forward ends by inwardly directed portions 2-2 which are joined to a medial forwardly extending arm 3, the forward portion of which is bifurcated into arm 4-4 which carry on their outer ends bearings 5-5 in which are journaled the shaft 6 of a circular saw I. The shaft 6 carries preferably a double pulley I.

Depending from the frame member 2-2 and forwardly extending arm 3 at substantially the point of juncture of these parts, are spaced arms 8-8 carrying on their lower ends journals 9-9 for rotatably supporting the shaft of a ground contacting wheel I0 which, it will be observed, lies in substantially the same place with the circular saw I.

Depending from each of the handles I rearwardly of the ground contacting wheel I0 are frame members I I-I I connected by frame members l2 and steadied by diagonal brace I3 which have their forward ends secured respectively to the members 4-4. Mounted upon the frame members I 2-I2 is an internal combustion engine I4, the pulley I5 of which is connected as by the double belt It with the pulley I mounted on the saw shaft 6. A fuel tank I 8 for the engine Hi can be conveniently mounted upon the upper side of the handle I adjacent the engine. Legs I'I-I I can ,be also provided on the handles I so that when not in use the saw will be supported by tl|1e ground contacting wheel I0 and the two legs I.

In operation it will be apparent that by grasping the rear end of handles I I the entire device can be manipulated like a wheelbarrow on the one ground contacting wheel I0 and approached at any angle to a fallen log regardless of the roughness of the ground. It will be further observed that by further elevation of the handles I-I the saw I can be depressed over the log to saw the same from the top downwardly and that by manipulating the handles I the angularity of the saw 1 with respect to the vertical can be readily adjusted so as to take into account the angularity of the fallen log with respect to the ground.

In actual construction it will be apparent that the structural details are subject to variation but the present embodiment has been found highly practical and desirable.

Having thus fully described my invention, I claim:

1. A single wheel support portable saw comprising a framework including handle members joined medially of the structure to a forwardly extending arm formed with a bifurcated forward end to receive the saw, a downwardly extending fork member connected at its upper end to the frame at the junction of the arms and saw supporting member, a single supporting wheel journalled in the fork member and means for supporting a motor below and medial of the handle members.

2. A wheelbarrow type portable saw comprising parallel handle members having their forward ends bent inwardly and joined to a forwardly directed saw supporting arm, a downwardly extending fork for a single wheel having its upper end joined to the frame at the junction of the handles and saw supporting arm, a wheel journalled in said fork, an engine supporting framework depending from the handle members rearwardly of the wheel supporting fork, and leg member depending from the handle members rearwardly of the engine supporting frame.
